The difference between ppx_deriving_protobuf and ocaml-protoc is that the
former generates a protobuf schema from an OCaml type while the later
generates the OCaml type from a protobuf schema. They are both using the
same runtime library for the binary encoding.

Although I have written ocaml-protoc as a personal project, it has been
used successfully in a professional context to interface with apache mesos.
